The Lowdown
Alright, this is Rusty, and I’m looking at what’s coming up for Jaconé. It’s a bit of a mixed bag, but there are some windows that are going to be really special.
First up, the water’s sitting at 73°, which is about average for this time of year, so no shocks there.
The action really kicks off on Tuesday afternoon (8th) with a S swell pushing 5 ft and a period of 10 seconds. The wind’s a cross-off from the ENE, so it’s clean but not perfect. The energy’s moderate at 602, so it’s a warm-up, not a standout.
Wednesday morning (9th) is where it gets interesting. The swell drops a touch to 6 ft from the ENE, but the period is a short 7 seconds. However, the wind goes glassy from the WNW. That’s the magic word. The combined energy is solid at 695, and the conditions will be glassy. This is a good time to get out, but the short period means the waves might be a bit jumbled.
Thursday morning (10th) brings a cleaner picture. Swell is 3 ft from the S, with a 12-second period – that’s proper groundswell energy. The wind is offshore from the NE, light at 6 mph. The water will be clean. The energy is 515, so it’s not huge, but that long period will make for some nice, lined-up waves.
Friday morning (11th) is the real highlight of the first week. Swell is 4 ft from the S, but the period stretches to 14 seconds – that’s a very long period groundswell. The wind is glassy from the N. The energy is a strong 742. This is going to be clean, powerful, and with good shape. The only thing to watch: that long period will make the sets a bit more spaced out, but it’ll be worth the paddle. Jaconé is exposed to the SE, so a S swell is a decent angle.
Saturday morning (12th) is still clean, but the swell drops to 2 ft with a 12-second period. Energy is low at 214. It’s glassy, but you’ll be working for those small ones.
Sunday morning (13th) is a big one. The swell jumps to 6 ft from the SSW, with a 10-second period. The energy is massive at 1080 – that’s very strong. The wind is a cross-off from the ESE. This is excellent, but it’s for experienced surfers only. At 6 ft, it’s pushing into the “too big for beginners” zone, and at nearly 7 ft, it’s getting serious. The conditions will be clean, and the power will be there, but it’s not a day for the faint-hearted.
Monday morning (14th) settles down to 5 ft from the S with an 11-second period. Wind is a light cross-off from the N. Energy is 754. Clean, solid, and more manageable.
The second week is more of a waiting game.
Thursday morning (17th) looks promising again. 5 ft from the S, 12-second period, and a clean offshore from the ENE. Energy is 647. That’s a good, clean session.
Saturday morning (19th) has a 3 ft S swell, 12-second period, and light cross-off wind from the NNW. Energy is 535. It’s small but clean.
Monday evening (21st) is a real surprise. The wind goes glassy from the SSE, and there’s a 5 ft swell from the E with an 8-second period. The energy is 370. It’s not the biggest, but glassy conditions are rare, and it’ll be super clean.
The rest of the second week, from the 22nd onwards, gets messy. The wind turns onshore, the swell direction shifts, and the periods drop. It’s a lot of short-period, onshore slop, so give it a miss.
Best on offer: Without a doubt, Friday morning (11th) is the clear winner. That long-period S swell with glassy wind is a dream. Sunday morning (13th) is the heavy hitter for the experienced crew, but it’s a beast. The Thursday morning (10th) and Monday morning (14th) are solid, reliable options too.
Rusty.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Jacone is 14 km (9 miles) from the city of Saquarema. If you plan a holiday in Rio de Janeiro, look for hotels and other accommodation in Saquarema. Saquarema has rooms for a wide range of budgets as well as car hire and transport links.
